Boulton & Paul
P.3£
/^^/^>ET another aircraft which will be seen at the R.A.F.
Ill Display at Hendon on June 25 is the Boulton
_U1_ Paul P.32, which is a three-engined night bomber
of all-metal construction, fitted with three of the
new Bristol " Pegasus " engines.
From the photograph it will be seen that the P.32 has a
somewhat unusual engine arrangement in that the central

engine is not placed in the nose of the fuselage, but on
the top centre-section. Of recent years there has been
noticeable a tendency to avoid the nose engine in multi
engined aircraft. There are various reasons for this, chief
among them being the fact that with the central engine
removed from the nose of the fuselage, the cockpits can be
so arranged as to give pilot and bomber a very much better
view, making the aircraft the equal, in this respect, of a
twin-engined machine. There was a time when certain
doubts existed concerning the soundness of placing one or
more engines so high above the centre of resistance, and
types produced many years ago with this engine arrange
ment were far'from being successful. However, the latest
types of aeroplanes having engines on or near the top plane
of a biplane have not shown any pronounced vices, and
the arrangement is now accepted as quite a permissible
one, while giving a number of advantages in other respects.
The Boulton & Paul P.32 is of the type of construction
which this firm has developed during a long period of
years, with high-tensile steel in the primary structure.
SEE
An undercarriage of the four-wheeled type is fitted,
springing being by Boulton & Paul oleo-pneumatic shock-
absorbing legs. Brakes are fitted on all four wheels, and
as there is a castoring tail wheel, the machine is, what
with outboard engines, remarkably manoeuvrable on the
ground.
Great attention has been given to the control system of
the P.32, and the machine is reported to be particularly
light on the controls. The ailerons have Bristol-Frise
balances, while elevators and rudders are servo-operated.
That the P. 32 is a large aircraft will be seen from the
following figures—the only ones which it is permissible to
publish at present.
The overall length is 47 ft. 6 in. and the wing span
100 ft. The height over the central engine is 22 ft., and
the total wing area 2,090 sq. ft. As the gross weight is
22,700 lb., the wing loading becomes just under 11 lb./
sq.' ft., and the power loading (at 3 x 555 h.p.) 13.7 lb./
h.p. The particular Bristol " Pegasus " engines fitted
each develops 555 b.h.p. at 4,500 ft.
THE HANDLEY PAGE H.P. 38 : This machine, produced two years ago, is still surrounded with a certain amount of
secrecy. It is a night bomber with high performance, and the arrangement of the fuselage and engines is such as to
provide monoplane view while retaining biplane manoeuvrability. Wing span 75 ft. Gross weight 15,600 lb. The
H.P. 38 will be seen at Hendon on June 25. (FLIGHT Photo.)
